Connector Descriptions

The following sections describe the use of each connector on the I/O Development Board.

J5, the Utility 1 connector connects to the Little Board/P5x Utility 1 connector (J16). It provides
connections to an on-board speaker, keyboard connector, reset switch, a connector for external -5V
and -12V power supplies, and a power LED.

If you have the Ampro Quick Start Kit, connect a ribbon cable between J5 on the I/O Development
Board and J16 on the Little Board.

If you install the Little Board on the Little Board Development Platform, it is not necessary to
connect Utility 1 signals to the I/O Development Board. The Utility 1 features are already provided
on the Development Platform.

If you connect J1 to J24 on the Little Board, you can use J2 to connect a PS/2 mouse.

Connectors J3 and J4 provide connection to USB ports 1 and 2 respectively. These are standard
shielded Type A connectors, the kind typically found on a host or hub. For details about the USB
ports, refer to the Little Board/P5x Technical Manual. To use the USB ports, you must connect a
cable from the I/O board’s J1 connector to the Little Board’s J24 connector.

The Utility 2 connector (J1) connects to the Little Board/P5x Utility 2 connector at J24. It provides
connections to the Universal Serial Bus (USB) ports (J3, J4), infrared interface (IrDA), and power
management switches (S1, S2, and S3).
